The crystalline landscape of a drug substance can dramatically affect development timelines, costs, and complexity.

While the most stable crystalline form is often preferred, identifying it is rarely straightforward. That’s where our thermodynamic expertise and advanced analytical tools come in, helping you mitigate risks and make informed decisions at every stage.

Our polymorph screening is tailored to your development stage and material constraints, combining systematic crystal form exploration with advanced solid-state techniques like XRPD, DSC, TGA, DVS, and NMR. This deep scientific approach reveals all viable forms, enabling confident selection of the most stable or phase-appropriate polymorph. From there, we support you with follow-on testing in stability, solubility, and dissolution, along with expert guidance on interconversion and long-term form stability. Whether you’re mitigating risk, preparing for regulatory submission, or strengthening formulation robustness, we help you move forward with clarity and confidence.

Why Choose Sygnature Discovery for Polymorph Screening Support?

We screen for a wide range of crystal forms – including anhydrous polymorphs, hydrates, and solvates – using varied solvents and experimental conditions. This comprehensive approach ensures that all potential forms are considered, including those that may emerge during manufacturing or storage. Identifying the thermodynamically stable or most phase-appropriate form is essential for formulation robustness throughout development. Beyond formulation, the polymorphic profile of your compound can also be a strategic asset for intellectual property. Sygnature Discovery delivers detailed solid-state characterization data (XRPD, DSC, TGA, DVS, NMR), to support:

• Patent applications

• Regulatory submissions (e.g., DMFs, INDs)

• Claims of novelty and utility
